When was CAN bus first used?

The Genesis of CAN Bus Technology: A Chronological Journey

In the realm of automotive communication, the Controller Area Network (CAN bus) stands as a pivotal technology that has revolutionized vehicle design and functionality. Its origins can be traced back to the early 1980s, when Bosch embarked on a mission to develop a reliable and efficient communication system for automotive applications.

1983: Bosch Initiates CAN Bus Development

The year 1983 marked a significant milestone in the history of CAN bus technology. Bosch, a renowned automotive supplier, recognized the need for a standardized communication protocol that could seamlessly connect various electronic control units (ECUs) within a vehicle. The company’s engineers began working diligently on a groundbreaking concept that would later become the foundation of the CAN bus.

1986: Unveiling at the SAE Conference

Three years later, in 1986, Bosch proudly unveiled its CAN bus technology at the Society of Automotive Engineers (SAE) conference. This pivotal event marked the official debut of the CAN bus concept, sparking widespread interest and enthusiasm within the automotive industry.

Collaboration with Intel and Philips

Recognizing the immense potential of CAN bus technology, Intel and Philips, two influential technology companies, joined forces with Bosch in the late 1980s. These partnerships proved instrumental in advancing the development of crucial controller chips, further solidifying the foundations of the CAN bus.

Conclusion

The CAN bus emerged as a transformative technology in the automotive landscape. Its genesis in 1983, unveiled at the SAE conference in 1986, and subsequent refinement through collaborations with industry leaders laid the groundwork for its widespread adoption. Today, CAN bus technology remains a ubiquitous communication protocol in modern vehicles, enabling efficient and reliable data exchange between various systems, enhancing performance, safety, and the overall driving experience.
